Short CV

## Research Interests

I am interested in geometric aspects of Stokes phenomena in singularly perturbed, non-linear problems. My work is motivated by a wide range of physical applications in both supersymmetric quantum field theory and free surface flows. In particular, I am interested in developing new techniques and methodologies to better understand exponentially small physical effects.

I have been/am interested in the following areas:
- Supersymmetric indices and connections to algebraic/geometric structures.
- Exact results in 3d N=4 theories and 3d mirror symmetry.
- Integrability and enumerative geometry in supersymmetric QFT.
- Singular perturbation theory, Borel resummation and resurgence.

I am currently a postdoc in Dr. Philippe Trinh's research group at the University of Bath.
